Toshiba Satellite M65-S821 WONT BOOT UP

When I press the power button on my laptop the blue light comes on for about 5 seconds and then goes off. The computer does not boot or make any noises. Sometimes after several tries the fan will come on for about 5 seconds and then when the blue light goes off the fan goes off. I have gone thru all the usual troubleshooting procedures and suspect it may be a motherboard problem. does anyone have any insights on this?

    Sorry for the confusion thehumble1. Here is what I checked out. I reset the Ram Memory chips no good; I replaced the Ram Chips no good; I removed the battery and tried to boot up with just the adapter no good. It was suggested I try to power on and press the F8 key 5 times no good. I also tried another adapter from another laptop no good. The fan will sometimes come on when you press the power button but when the blue light goes off the fan stops also. There are no external devices or ad-ons I will look at the fan and see if that could be part of the problem. I have not tried pressing the power button 5 to 10 times so i will try that out also. Most of the research I have done on the internet suggests that it may be the motherboard. But I wanted to get some more suggestions before I go and invest in a new motherboard and it be something simple.

    Tried everything you tried and I believe it's the power supply, which unfortunately is part of the motherboard. Wish I had a solution--warranty expired 1 month earlier.

    Dear, thehumble1. I guess I just had humble pie!

    Sorry this is my first time on this board, I answered a few questions as I was looking to see if someone had the same trouble as I did and if they had an answer, I saw this and clicked “I have the same problem” I wasn’t really prepared so I didn’t take the time to list everything I did “my bad” I will try to do so if I need help in the future.

    But just so we are clear It does not shut down, the green power light comes on, the hard drive spins up but I get no video on the screen or on an external monitor.

    Here is a list of the things I have done that have not helped. Nothing is hooked to or connected to the laptop.

    The first thing I did was remove both memory chips and reseat one, than I tried the other. I tried without memory.

    I took out the battery and pressed the power button a few times.

    I used another working power supply.

    The battery charges fine.

    Hooked up an external monitor and pressed the correct keys to start it.

    I saw in your Google solution #3 is my best guess motherboard, but I tried to take a shot just incase someone knew of a Toshiba fix for this.

    So that is my complete tale of woe, thanks for trying.

    Kevin My Computer Guy.

You didn't list what you did do, so you might have already tried this, but I think it's always a good idea to try re-seating the RAM and then try different RAM in the computer if you can. The symptoms seem to be identical to those caused by bad RAM sometimes. It might also be a heating or fan problem which, when detected by the motherboard, activates an auto shut down.

Also, make sure the power supply is producing the proper amperage and consistent voltage. some power adapters provide a signal to the computer, along with power, that is critical as well, so there is a slight possibility that the adapter may be causing the problem. Actually I'd follow this further. If the battery is almost dead and the adapter not working, those are the exact symptoms you'd get. Do you know if the battery is charged and the adapter works?

I'm assuming you've removed all external devices and cards or other ad-ons.

Did you try taking the battery out, unplugging it and pushing the power button 5-10 times? This might help reset some settings.

And, if you already have done any of these, please list them so people, like me, don't waste our time giving you incorrect answers, because you didn't take your time to list what you've done.


Google it first. because look what popped up.

    dang. sounds like you did do a thorough job of testing. That keeps moving the most probable solution towards a motherboard replacement, which, out of warranty, is cost prohibitive. An idea could be to buy the same model on eBay that has a cracked screen and pulled hard drive. It could be a cheaper fix.

    but if you think it's a dead motherboard, why not strip the computer down and test a few things, such as CPU heatsink, fans and component connections. good luck.

First you shoult remove the battery (it could be short circuited) then try powering up, if it's not working check the AC adaptor with a multimeter to verify voltage (compare with what it is ritten on the AC adaptor) last thing you should remove everything you can (RAM, HARD DRIVE, NIC's, CD ROM, etc...) than try powering up again if it power's up than put back ONE DEVICE/MODULE AT A TIME TO TARGET THE FAULTY DEVICE. if nothing worked i'm sorry it's dead.

Good luck!

Sometimes Satellites get a little flaky when on battery power. If you haven't already, plug in the power cord with the notebook cold - meaning off for about a minute. Boot the notebook and try to do the setup with the power connected. If that solves it, it should work fine when you switch to battery power. If it doesn't, repost with your results.

Will not turn on, no lights at all

Try to remove the battery, and plug it into the wall. If it then boots, your battery has failed. This happens frequently. If it still wont boot you will need to take to someone to see if the board has died or other issues. Hope this helps

Toshiba Satellite M65-S821

When u send it out, did u take note of what u had.Memory,hard drive(h/d) size, etc. A virus only attacks the software ( changes & or damages ) drivers. If the virus damages the h/d , it is PROBABLE to physically damage it, but not usually possible!! goto the Toshiba web site, u will have to buy it, they don't like to give those things away.
